Neurowerk EMG/EP Systems

A portable version or a complete in office/clinic (2 or 4 channel) neurophysiological measuring system for EMG, NCV and Evoked Potentials for use both in the clinic and in the doctor's practice, with a streamlined trolley. The system provides the complete range of methods needed in the daily routine diagnosis of neurological functional disorders.
Straightforward intuitive operation combined with high time efficiency are just as much highlights of the system as the amplifier and high ADC resolution to record any electrophysiological signal you need.
